Mehrsprachige Oberfläche + lokalisierte Gericht-/Bereichsnamen

Alle Seiten und Komponenten (öffentliche Speisekarte, Login, Kantinen-
und Admin-Bereich, eigenes Konto) verwenden jetzt die Wörterbücher aus
lib/i18n statt fest codierter deutscher Texte. Gerichte/Bereiche/
Allergene/Zusatzstoffe zeigen den Namen zur aktuell gewählten Sprache;
Gerichte- und Kennzeichnungs-Formulare bekommen Englisch-/Polnisch-
Felder mit Übersetzen-Button (siehe vorherigen Commit). Datumsformat-
ierung (formatDateLong) nimmt jetzt ein locale-Argument statt fix
'de-DE'.
